矢量传感器增益校正与补偿

Calibration and remedy for vector-sensor

矢量传感器与每个通道的接收功率与信号的到达方向和极化状态有关,但信号的到达方向和极化状态很难精确控制,原有的基于全向天线估计通道增益的方法不适用于矢量传感器的情况。提出了估计矢量传感器通道增益的方法,并从电磁波特点出发导出了各通道增益的计算公式。数值仿真结果证明了该方法是有效的。

The receiving power of vector sensors is relate to the DOA （Direction of Arrival） and polarization of signal, both of which are difficult to control. As the available methods for estimating the channel gains of the scalar sensors are not suitable for vector sensors, a novel technique for estimating channel gains of vector sensors is proposed and computational formulas of the channel gains are derived in this paper. Finally, Simulation results verify the effectiveness of the new algorithm.
